CONVERTIBLE CHAIR.

Application filed March 10, 1924.

To all whom it may concern Be it known that I, Gonnox Axons Ross common,a subject of the King of Great Britain, residing at 27 GainsboroughRoad, hadwell Heath, Essex, England, have inrented new and usefulImprovement in G011- vertible Chairs, of which the following is aspecification.

This invention relates to articles of furniture and refers moreparticularly to articles of furniture which can be used for a definitepurpose and can be converted to form another article so as to be usefulfor a different purpose.

The movable portion of the chair is advantageously constituted by theseat and back of the chair.

In one constructional embodiment of the invention the improved articleof furniture regarded as a chair comprises four legs and top and bottomskeleton frames one of which serves as a base when the article is beingused as a chair and both of which are adapted to act as supports and endwalls when the article is turned into position to form a cot. The chairlegs are connected pairwise by cross slats to form the two sides andbottom of the cot and a portion of the top skeleton frame is formed as amovable tray or support for the babys toys or the like. The seat portionis pivoted or hinged to or near to the two front legs and the back portion is pivoted or hinged to the seat portion the arrangement being suchthat when it is desired to form a cot the article is turned so as to besupported on the top and bottom skeleton frames and the seat portionturned on its pivots or hinges so as to form a part of the bottom of thecot the back of the seat portion forming the end of the cot.

In order that the invention may be clearly understood and readilycarried into effect I will now describe the same more fully withreference to the accompanying drawings which illustrate severalstructural embodiments of the invention.

In these drawings:-

Figure 1 is a side elevation of one form of my improved article offurniture serving as a babys chair.

Figure 2 is a side elevation of the same article converted into a babyscot.

Figure 3 illustrates a slightly modified form.

Figures 4 and 5 illustrate two further constructional forms having.expanding Serial No. 698,321.

sides. Figure 4 illustrates the article actually serving as a cot.

The so-called chair-cot has four legs as usual, a top skeleton frame 1formed with a movable tray or support 2 for the babys toys or the like,and a lower skeleton frame 3 serving as a base. The legs are suitablybraced or stayed pairwise as to three pairs to constitute the two sidesand bottom of the structure when acting as a cot as in Figures 2, 4 and5. The forward ends of the side members of the bottom frame 3 arepreferably provided with wheels, rollers, castors or the like 4 tofacilitate moving the structure about either as a chair or as a cot.

5 is the seat portion and 6 the back of the chair these parts beinghinged together at 7 and the seat being hinged to the top front crossstay at 8 or alternatively pivoted by means of bolts running through themain frame front legs at 8. 9 is a pad on the back of the chair which isattached to the top back cross stay by a hook or the like at 1.0. Frominspection of the drawings it will be readily seen that the chair isconverted into a cot by swinging the parts 5 and 6 into theiralternative position in which the free end of the chair back is againattached to the top back cross stay by a hook 11 or the like. Obviouslyinstead of hooks any other convenient looking or fastening devices maybe used. As will be readily understood the top and bottom skeletonframes of the chair become the end walls and supports of the cot.

A three piece hinged mattress 12, 13, 14. may be attached to the bottomof the cot by means of tapes, clips or other suitable fastenings so thatwhen the cot is required to be converted into a chair this mattress maybe folded over and remain within the chair. The enclosed space formed bythe hinged mattress when folded may be suitably utilized to contain thechilds pillow, bedclothes and the like.

It is to be observed that the seat 5 projects beyond the front crossstays and beyond the rear edge of the tray 2 to ensure the babys beingretained on the seat. Figure 3 illustrates a slight modification inwhich the seat does not project much but the tray 2 extends back overthe seat to a considerable extent represented bv the hinged portion 2',the function of the overlap being the same as in Figures 1 and 2. Inconverting the chair snown in Figure 0 into a cot the hinged portion 2of the tray is folded back, and the seat is swung about pivots ortrunnions 15 constituted by bolts passing through brackets or anglepieces 16 and through corresponding brackets extending downwardly fromthe underside of the seat.

In Figures i and 5 two ways of expanding the cot laterally are illustated by way of example. In Figure at the sides of the cot are shownattached to the main structure by toldable arms 17' whilst in Figure 5the sides are shown as constituted by cranked stays 1S and bar 19 thelatter being in tact a back leg of the structure when serving as achair. The entire row of cranked stays can swing outwards about theirrespective sockets and thereby add width to the cot, as will be readilyunderstood. When in opened position the sides are held in any suitablemanner, "for example, by red 20 and angle iron 21.

hen laterally expansible sides are employed as shown in Figures 4 and 5,the longitudinal bars or trout chair legs may be duplicated and crossbraced to increase the strength.

It extra length is required the end wall at the toot of the cot that isto say the chair back portion of the structure can be let down from theposition shown in Figure 2 into a horizontal position and be supportedfrom the floor by a folding leg. This extension may receive an extrasection of the mattress or the pad on the seat back may be detachableand be used as a mattress extension.

It will be understood that the above de scribed constructions are not tobe regarded as limiting the invention thereto but as i11- dicatiug onlythe manner in which the invention may be carried into effect. Also amsuitable material may be used in manuhicturing the so-called chair-cot,as for example entirely square or round wood bars etc. or tubular metalor partly wood or partly metal.

llhat I claim is 1. An article of furniture convertible at will into aba cot or a chair comprising a framework, :1 chair-seat member hinged atits front edge to said framework, a chairhack member hinged at, itslower edge to the rear edge oi said chair-seat member and means forsupporting said members in alternative chair-functioning andcotfunctioning positions, so that the desired conversion may beeffected.

2. An article of furniture convertible at will into a babys cot or achair comprising legs braced pairwise as to the front pair and the twoside pairs, a seat member hinged as to its torepart to a cross brace ofthe front legs, a back member hinged to the rear part or" said seatmember, means for supporting said members in alternativechair-functioning and cot-functioning positions and means whereby thearticle may be expanded laterally when functioning as a cot.
